在Selenium C＃无头Chrome中提取表

Question

I am doing automation of a site and I did all of it. At finally I am storing the table in List and it is working fine without headless Chrome. But when I changed my Chrome browser to "HEADLESS" I am getting empty "td" of table some of them showing and some of them is missing

ChromeOptions option = new ChromeOptions();
option.AddArgument("--headless");
IWebElement myTable = driver.FindElement(By.XPath("//*[@id=\"trades-view active\"]/table/tbody/tr[1]/td[5]"));

I am attaching both the Screen shots. In first screen shot Location { X=666 , Y=1112 } and Locationonscreenoncescrolledintview { X=659 , Y= 512 } This is the case when I am getting the whole table without any problem. enter image description here

But when I want to change the browser in Headless state then I am getting Location { X=0 , Y=0 } and Locationonscreenoncescrolledintview { X=0 , Y= 0 }

enter image description here

I shall be very thankful to you if you suggest me any changes to do it correctly.

Thanks

I think you may need to set the window size before navigate to the web.

ChromeOptions option = new ChromeOptions();
option.AddArgument("--headless");
option.AddArgument("--window-size=2160,3840");
IWebElement myTable = driver.FindElement(By.XPath("//*[@id=\"trades-view active\"]/table/tbody/tr[1]/td[5]"));

Web application may display only some default content and show the remaining when users scroll to the position.
